Application filed Ziunc 1'7, 1912, Serial No. 774,2?2.

To (/17 74"]107/2 it in (1 concern Be it lcnown that I, Geonon GUILD, citizen of the United States, residing at South Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Jacklocks, of which the following is a specification.

This invention has reference to improvements in jack 'blocks used for the purpow of holding the wheel of a car to the rail in jacking up the journal box, to remove, renew or replace the journal hearings or hrasses.

The primary object of the invention contemplates the provision of a specially constructed stand or base which can be applied to any form of car wheel, upon either side of a car, and which is not dependent upon the relative position of the wheel with re spect to the tie, but is held entirely by the wheel'and rail.

A further object of the invention resides in the provision of a device of this character which comprises but a few simple parts unlikely to become impaired and which can be readily applied without necessitating the use of any special tools.

The invention consists briefly of a specially constructed block or base, a lifting screw carried by the said base, and means arranged upon the said base for fastening the latter in proper position. to the wheel and against the rail.

The above and additional objects are accomplished by such means are illustrated in their preferred embodiment in thenccompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings'wherein -like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of a car wheel, illustrating the application of the invention; Fig. Q is an. end view, the rail being shown in section; and ifi'is a detail perspective viewof the base or block.

Referring now to the drawings, wherein is illustrated the preferred form of my invention, the numeral 1 designates a ca wheel of the ordinary type, 2 the axle upon which Specification of Eetters Patent.

To accomplished this result 1- prom ride a block or base portion designated in its entirety by the numeral 4, the sai ,hase comprising laterally projecting extensions 5 in the extremities of which openingsor holes 6 are provided, and tln'ough"v v'hich wheel engaging hook-shaped members '2" entend, the said members overlapping the flange of the wheel and preventin" oscillatory movement of the wheel duringtho jacking up of the journal box. An adjustable nut 8 is arranged over the threaded eztill tremity of each member 7 for drawing the curved or extended portion thereof into lirrn engagement with the inner face of the car wheel. A depending portion 9 is also formed integrally with the base 4 of the device, this portion likewise having a threaded opening 10 formed therein through which an adji1stable exteriorly threaded screw bar 11 er;- tends, one extremity of the said bar engaging the web of the rail upon which the car wheel is resting for supporting the entire base against lateral movement, the adjustment of the said bar 11 being controlled through. the medium of a head 12 provided therefor,

The base 4 is further provided with a for" ward extension 13 likewise formed intogrally therewith, the said extension having an interiorly threaded bore 14: extending vertically thercthrough, through which the lifting screw 15 of the device extends, the screw having the usual head 16 formed thereupon for engaging the under face of the journal box 3 for elevating the latter independent of the car wheel for removing or repairing the hearings or brasses when occasion demands. To prevent vertical or upward movement of the car wheel during the operation the elevating screw 15, a flange or projection 17 extends inwardly from the base 4 of the device, the said flange overlap ping the annular flange of the car wheel or fitting within the recess ordinarily formed within the outer face of the car wheel, the engagement between the said projection and. the said annular flange of the wheel retain lll h ner above set forth.

"ing, the latter in engagement with the rail upon which .it is supported.

In operation, it will be seen that the base 4 is first positioned with the projection 17 overlapping the said annular flange of the wheel, whereupon the threaded bar 11-is adjusted to firmly enga e the rail in the manifter adjustingthe bar 11, the extensions of the hook-shaped members .7 are drawn firmly in en agement with the inner face of the car whee by the operation ofthe nuts 8, which with the said bar 11 fastens or looks the base to and upon the car wheel and rail upon which the car wheel is wupported. The base having been positioned in the above manner the head 16 of the lifting jack is turned and in this manner the journal box 3 is lifted or jacked up to allow the brasses or hearings to be acted upon as desired.

It will be seen from the above, taken in connection with the accompanying drawings that the device is not dependent for support upon the position of the car wheel with respect to the cross tie, as the entire block is supported by its engagement with the wheel itself and the rail; that the wheel is held against lateral, vertical and oscillatory movement by the severalelements comprising my invention ;-and that the block or base when arranged over thefi'wheel and rail in the proper manner efi'ets -a rigid support for the lifting screw by means of which the journal box is raised or elevated.

- It will be understood that the above description and accompanying drawings comprehend onl the general and preferred embodiment o my invention and that various minor changes in the details of construction, proportion and arrangement of parts may be madewithin the scope of the appended claims and without sacrificing any of the advantages of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent,'is

1. A car wheel jack-stand including a support member, adjustable means carried by said member and disposed for engagement with the rail upon which the wheel is supported to lock the said member against lateral play, adjustable means carried by said support and disposed for engn'rement with the periphery of the car wheel to lock the support member against longitudinal play, means adapted for engagement with the wheel to lock the support against vertical play, and means operable upon the support for raising and lowering the journal box of the wheel axle, as and for the purpose set forth.

2. In a car wheel jack-stand, a base support member disposed to extend in parallel relation to the car wheel acted upon, :1 lateral integrally formed extension, means 0perable upon said extension for raising and lowering the journal box of the wheel axle, side extensions integral with said base sup-'- port, a hook-shaped member adjustable upon each extension, the said members being so formed as to overlap and engage the periphery of the wheel inspaced relation to its rail support to prevent oscillatory movement of the said wheel during a jacking operation, a bolt adjustable upon said base support, said bolt being adapted for engagement with the said rail to maintain saidbase against lateral play, and a tongue integral with the said base and disposed for engagement with the wheel to lock the same against vertical play, as and for the purpose set forth. a

In testimony whereof I ailix my signature in presence or" two witnesses.
